Portfolio of our projects

Lithuanian museum of ethnocosmology

Lithuanian Museum of Ethnocosmology is the unique futuristic building complex near Molėtai, Lithuania.

Before the reconstruction of the centre, building operators faced with the humidity and temperature problems. An effective solution at minimal cost was required; moreover, ventilation and air conditioning equipment had to be adapted to the exclusive futuristic cafe interior designed by architect studio EKSPO BALTA.

Scope of works:

  • Reconstruction of the heating, ventilation, and air conditioning systems in the observation platform.

Short description of the project:

  • We have developed the moisture control solution based on recirculation and a special control algorithm.
  • The interior has been preserved with the ceiling fan coils and ventilation grilles hidden in niches.
  • Also, a number of energy-saving solutions were applied, and the client was provided with the recommendations for the future reduction of infiltration and possibilities to use natural cooling.
  • The reconstruction was scheduled during the period of adapted building operation

Multifunctional building – ongoing project

Our object is multifunctional building, situated in the Old Town of Vilnius. The building consists of residential and recreational areas, art gallery, and art storage facilities.

During the reconstruction of the building and its adjoining, the main focus was put on the preservation of the cultural heritage of the building and its integration into the single style of the Old Town.

Scope of works:

  • Heating with air supply system SCHRAG; mechanical ventilation and humidification system in the art storage and exposition facilities; ventilation and moisture control system.
  • Geothermal heating station; gas boiler room; main heating and cooling pipework and its auxiliary equipment.

We use consolidated drawings in 3D in order to save on the useful floor space allocated to technical premises and to avoid conflicts during the installation of engineering systems.

Restaurant BIZARRE

The restaurant BIZARRE is noticeable not only for the delicious presentation of two different cuisines, but also for the uniqueness of the interior. It is located in the center of Vilnius, Pylimo st.

The premises of the restaurant are equipped with modern energy-saving engineering solutions. The operating costs are significantly reduced as the heat is recovered from the air removed from the kitchen food production area and reused to heat the fresh air supplied to the quests of the restaurant. Moreover, the building has a highly efficient VRV air conditioning and heating system with zonal temperature control.

Scope of works:

  • Ventilation system with liquid-coupled heat exchangers.
  • Installation of the system ensuring technological air exhaust from the Kitchen hoods (supplied with the TurboSwing fat separation and assembling technology) and air supply to the working areas in the kitchen.
  • Freon-based air conditioning/heating system VRF.
  • Centralized Liquid-coupled heat recovery system.

Administrative premises are located in the very heart of Vilnius Old Town. Here the ventilation and air conditioning systems were reconstructed.

Scope of works:

  • Adaptation of the room ventilation systems to the new floor plan.
  • Installation of the air-conditioning system with water based fancoil units.

Production premises for the pharmacy company

In a functioning building, internal engineering systems were installed for the D-class "clean rooms" in the production facilities.

Special wall panels were installed to separate clean and common rooms and internal premises. In the premises, the internal walls were sealed in order to maintain adequate overpressure towards surrounding areas. The hygiene of the ventilation system is achieved by installing Hepa filters of the appropriate class both in the air ventilation unit itself and in the air diffusers.

Scope of works:

  • Ventilation system with air recirculation, H14 class Hepa filters, VAV valves.

GOURMET restaurant area in the shopping and entertainment center Panorama

The Panorama shopping and entertainment center has a new concept catering area, which has built up 20 quality food stores and boutiques. Here,the visitors are invited to taste freshly made meals and get a variety of exotic products to take away.

Unique energy-efficient technical solutions have been implemented during the project. In order to recover the heat from the air exhaust system, the kitchens were equipped with the hoods with the efficient cyclonic filters and UV system that causes contaminants in the air to be destroyed, resulting in reduction of odour emissions to the surroundings as well as grease and fat reduction directly in the hood and in the ductwork.The reduction of grease not only reduces contamination of the system, but also protects against fire as accumulated fats often cause fires in operating catering establishments.

Scope of works:

  • A ventilation system with run-around heat recovery has been installed.
  • The technological air exhaust is assured by cyclonic filters integrated in kitchen hoods, air supply using the AirJet function and UV-C lamps generating ozone for grease reduction.
  • The visitors‘ zone has been equipped with a water-cooled air conditioning system.
